What is the N:C ratio of a rubricyte?

The N:C ratio reflects maturation of erythroid cells in the bone marrow: as the cell matures, the nucleus becomes smaller and the cytoplasm increases due to hemoglobin synthesis. A rubricyte is a late erythroblast in which the cytoplasm has expanded and begun to color with hemoglobin, but the nucleus is still present and more condensed. This yields about four parts cytoplasm to one part nucleus, a 4:1 ratio. Earlier stages have a larger nucleus relative to cytoplasm (higher N:C, like 8:1 or 6:1), while later stages show a smaller nucleus relative to cytoplasm (around 2:1). Therefore, 4:1 is the typical N:C ratio for a rubricyte.
